A movie titled Chatroom starring Aaron Johnson might not sound like something that you'd normally see on the Croisette, but when you find out it's a dark thriller about teens who use the web to manipulate each other into suicide - directed by Ringu's Hideo Nakata no less - then it all starts to make a bit more sense.

The film gets its Cannes premiere in the 'Un Certain Regard' category, and below we have a trio of stills to tease you with. The supporting cast is pretty (and pretty) impressive, too, with Imogen Poots, Skins's Hannah Murray, Megan Dodds, Tuppence Middleton and Ophelia Lovibond all offering support.
